Battery? Alternator? Multimeter? Help!!

[Longroof79]

Steve,
Oddly enough I had the same problem. My GEN. light was not lighting up when I turned the key to ON. My CS-130 alternator was charging. I took the gauge cluster apart hoping to replace the bulb. I tested the bulb and it was good. I even replaced the bulb, put it back together and the alternator stopped charging. I found that the brown wire was open. I did put the ohm meter on that lead and there was nada. So then I decided to run a new wire off the fuse box to the alternator plug "L" connection along with a inline resistor. Hit the key, started up, put the meter on the alternator...14.5 volts.
Prior to that I ran a jumper wire to the green oil pressure warning light. Knowing it was a switched source with some resistance (warning light), I also was able to pull 14+ volts off the alternator.
Somewhere I read that Patmckinneyracing also encountered the same problem and discovered an open charge wire. He also ended up running a new lead and was good to go.

I have essentially done the same thing to my camaro when I put the autometer gauges in. But I metered the brown wire all the way back in the cluster wires and hooked it to the signal spade on the new voltmeter and its been charging good every since. I sent Santos a youtube of how I got mine to work, so with that and everything on this thread im fully confident he can get this fixed properly.

Thanks for your help, Antoine.
Hopefully between our collective information, Santos will be back in business. :wink:

Hey Jack what where the ohms of the inline resistor I ask because my factory setup had a gauge not an idiot light.

Antoine,
The resistor I used was a 68 ohm, 2- watt. Painless wiring uses a 82 ohm, 5-watt with their adapter. Radio shack is a good source. But any good electronics supply should have an assortment of resistors, etc.
I used what I used because it was the closest they had in stock. It could be ordered if you don't need it right away.
Could you post your video? I'd like to see how you wired yours.

Jack, I didn't use a resistor due to my original setup have a gauge and not an idiot light. I asked because I believe Santos would need a resistor because of his factory idiot light, I'd hate to see his alternator blow up because of a 3$ part. As for the video I will post it when I get home, due to some bar language I'd rather reshoot it lol.

Antoine:
My ES82 pigtail has the resistor in it when i got it a Napa i made sure i got it with the resistor since i have no idiot light..

BUT HURRAYYYYYYY!!!!! I just finished up and its all working, u dont know how excited i am.. This issue has been kicking me in the butt, and puts me down easy, sometime i just want to give up!! But u guys made it easy for me.. Ya"ll got me.. Big shout out to "Longroof79" & "Antoine" for textin me and keeping me posted and on my toes!! Were up a good!!

Malibu off:

Malibu on🙂

When my gauge went all the way to 14vlts i knew we got it 🙂 it was always at 12v.

THANKS AGAIN!!

Yahoooo!! I'm happy for you, Bro. We knew you'd get it eventually. Glad I was able to help. Had I been out there, I'd be right next you... 😀 Nice going!
Now get out there and enjoy your ride. 😀

Antoine,
When Santos disconnected the original plug going to his gauge cluster. He killed his GEN. warning light circuit, which in turn did not excite, or energize his alternator.
He definitely could not continue to run it that way, or his alternator would have been toast.
